Directions

Directions (Latin directio — "direction"; Solar Arc Directions; German Sonnenbogendirektionen) is a predictive technique in which natal points (planets, axes) are advanced at a fixed speed.

Solar Arc Direction

The most widespread variant. Solar Arc Direction is the most widespread variant:

• All natal points advance by the same amount = the current Solar Arc (approximately 1° per year, but the exact value depends on the speed of the Sun on the day of birth)
• When a directed point reaches a natal planet or a midpoint (T092), an activation occurs: an event manifests
• Orb of precision: 0°–1° (narrow, after Ebertin)

Historical Types of Directions

• Primary Directions — based on the Earth's daily rotation, the most complex to calculate, used by Ptolemy
• Symbolic Directions — 1° = 1 year (the simplified version)

Use in Cosmobiology

Ebertin's main tool. In Ebertin's Cosmobiology (#42), Solar Arc Direction is the main predictive instrument alongside transits and midpoints.
